5 Select a retrieve rate to achieve the desired application
rate. (see example on pg. 16)
• Determine the precipitation amount you require in inches.
• In the gun performance chart, pg. 17, find the gallons per minute you are pumping by
crossing your nozzle size with the pressure you have at the gun .
• From the “ TIME REQUIRED TO WATER ONE (1) ACRE ” chart (chart #4, pg. 18), find the
time required to cover one (1) acre by crossing your GPM (from the previous step) with
your desired application amount.
• In the “ HOSE RETRIEVE RATE ” chart (chart #5, pg. 18), find the required hose retrieve
rate by crossing the “ TIME REQUIRED ” (from the previous step) with the lane spacing you
are using.
6 With the engine running adjust the pulley control knob until the speedometer reads the
required retrieve rate (from step #5)
The control knob should maintain its position when released. If the control knob posi-
tion changes on its own, an increase in drag on the control stem may be gained by tightening
the drag adjustment screw (arrow “A”, top illustration).
As the hose is un-spooled to prepare for the
next irrigation cycle, the compensator frame will follow
the hose level. At this time, the compensator control
cable, the cable drive arm, and the pulley cam do not
move (the engine pulley cannot close against the drive
belt). As soon as the engine is started, the reset spring
will cause the pulley cam to return to its’ “
START ” posi-
tion (at the top of the cam ramp). If the cam does not
reposition properly it can be adjusted. This is accom-
plished by changing the length of the push-rod.

During the hose retrieve cycle, the compensator
frame rests against the hose on the drum. As each layer of
hose is rewound, the compensator frame moves outward with
the hose. This movement causes the pulley cam to rotate a
measured amount, allowing the pulley to open slightly. This
changes the diameter of the pulley. The change in pulley di-
ameter changes the overall drive ratio which keeps the hose
retrieve rate constant (compensating for the increase in net
drum diameter). This process repeats for each layer of hose.
CAUTION
DO NOT adjust the pulley control knob unless the engine is running. Permanent damage
to the pulley may result.
